How, in a horizontally opposed engine with an external oil sump (like on
the C85 or 0200 or lots of others) do the crankshaft lobes "splash" oil
anywhere meaningful?

Disclaimer: I have no specific knowledge of the engine models mentioned.

The oil that's pushed under pressure through the crankshaft rod and main
bearings has to go somewhere. I picture it as a sort of whirling fog of oil
droplets inside the crankcase.

Specifically, *don't* picture the various crankshaft protrusions actually
contacting the surface of a pool of oil, that's not what happens.

The cam has to be lubed by some other mechanism.

The cam bearings have their own oil passages and are lubricated under pressure
from the oil pump. The cam lobes have no such lubrication.
